The best thing about know max is its user friendly interface with all required features available in one place for easy use by customer service representatives or any other employees working within this organization.
It's not so much expensive but it has some minor bugs like slow response when we try to send an email from our account page. I would highly recommend anyone who wants quality product over cost factor should go ahead with knowing maxim since they have good experience of using them. As per my personal opinion i can say there nothing bad about knowing maxim products apart form few issues related to speed while sending emails through web portal.
